Title: Path valve for single-acting consumer - has relief channel connected to second path valve by spring loaded valve
Inventor: BRAKEL KORNELIUS
IPC: F15B13/01
Filed: 1974-10-18
Abstract: The path valve has a valve member, controlling the connection between two outlets, which is spring-loaded in the direction of closing, and moved into open position by an actuator. The valve member is in active connection with a relief piston. The second outlet is connected to a second path valve, the control slide of which is moved by the actuator between neutral-, up-, and down positions. A relief channel is connected to a spring chamber on the relief piston and is also connected to the second path valve. In neutral position of the control slide this connection is in contact with the second outlet of the first path valve. In up position the connection of the second path valve is only connected to the return connection, while in down position, it is in contact with that connection, and the second outlet of the first path valve.

Title: Optical instrument reflector for calibrating smoke meter - has surface whose reflectivity reduces progressively from outside inwards
Inventor: TRILLER ADOLF
IPC: G02B5/12
Filed: 1974-10-21
Abstract: The reflector (12) for use in optical instruments, partic. in smoke meters for calibration tests, in which a bundle of light rays is directed at the reflector and received, has a reflective surface whose degree of reflection decreases from the edge towards the middle. The reflector is circular and the decreasing degree of reflection is formed by two areas, one of which (12a) is non-reflective and the other (12b) is a good reflector. The magnitude of the light receiving and reflecting areas is adjustable through an iris diaphragm arranged in front of the reflector.

Title: Valve operation system especially for ICE - uses electromagnets in place of conventional cam and rocker gear
Inventor: KLEMM WOLF
IPC: F01L9/20
Filed: 1974-12-11
Abstract: The opening and closing may take place magnetically by reversing the polarity, thereby saving the energy required to overcome the closing spring pressure or a return spring may be provided. The advantages claimed are the omission of the conventional cam and rocker gear and the face that a valve opening and closing time can be selected which is most suited to engine working conditions. The plunger coil (MK) is fixed to the valve shaft or can be part of it, or alternatively able to slide on the valve shaft whereby the valve is held in the closed position by a return spring. The magnetic coils could also be fitted laterally and actuate the valve by a two armed rocker gear.

Title: Blow moulded plastic containers with tear-off tag - where tag is formed independently of surplus, and may be looped
Inventor: NAUMANN WILLI
IPC: B29C49/50
Filed: 1975-01-21
Abstract: A tag of tearing off a calibrated strip similar to a sealing ticket from the neck of a vessel, which is formed, filled and closed by blow-filling techniques, is formed in two stages. In the blow mould, the stretching arbor presses out the material from the zone of the vessel neck into a cavity in which a rib forms a depression for a loop. In the following tool with the attachment for forming and closing the screw cap, a radially displaceable cutter releases the tag by cutting part way through the projection formed in cavity. No expensive tooling is required. The use of spew which tends to create difficulties as regards the sealing of the vessels is avoided.

Title: Liquid radioactive power station waste concn. - by evapn. and mechanical sepn. to minimise solid residue
Inventor: BAATZ HENNING DR
IPC: G21F9/08
Filed: 1975-05-10
Abstract: A method or removing liquid, radioactive waste from nuclear power stations operates on the principle of concentration in an evaporator, collecting the concentrate and then placing the collected radioactive waste together with a solidifying agent in a storage vessel. The concentrate is mechanically dried to give a solids fraction and a liquid fraction; only the solids fraction is mixed with solidifying agent and placed in the storage vessel, while the liquid fraction is recycled to the collecting tank, optionally via the evaporator. Transportation, solidification and final storage of the water fraction in the liquid waste is rendered unnecessary. Thus the total quantity of radioactive concentrate to be handled is reduced. A considerable savings in expensive manipulator handling of solid components in hot cells is achieved.

Title: Distance measurement of embedded particles - using radiation source and scintillation counter output to control pulse generator and counter
Inventor: KOROPP NORBERT
IPC: G01D5/48
Filed: 1976-03-04
Abstract: The distance measuring appts. for determining the separation of embedded bodies in work-pieces consists of an X-ray of Gamma-ray source (1) whose output is focussed via an aperture (2) onto a work-piece moving on a conveyor driven by a stepping-motor (10). A second aperture (4) andscintillation counter (5) are positioned on the other side of the work-piece to detect the absorption due to the presence of the body (6). A rate-meter (7) and level detector (8) set to certain limits control a pulse generator (9). The generator, whose output is counted (11) and also drives the stepping-motor (10) is stopped for a short time when a body is detected in the workpiece. The pulse count between each stop position is directly proportional to the distance between embedded particles.

Title: Rubbish tip internal settlement measurement - uses hose embedded in tip allowing position measurement by water pressure test
Inventor: WIEMER KLAUS DIPL ING
IPC: G01C5/04
Filed: 1976-03-13
Abstract: A method of measuring the settling positions of a number of test points inside a rubbish tip over a period of years, uses hoses embedded in the tip. A hose (5) is embedded in the rubbish tip, and this can be filled with water through a valve (1), near which an outlet valve (2), measurement tank (3) and manometer (4) are situated. Where the tip is below ground level, and so below the water outlet valve (2) level, a pump (8) is also attached to the arrangement. By observing the manometer pressure where the hose is full, removing a measured quantity of water from it, and observing the pressure again, the vertical position of a test point (7) which the hose passes through, can be ascertained. Over a period of time, this gives the settling behaviour of that test point.

The electrode arrangement is mounted stationary in the pptn. chamber and comprises a first cathode system and a second cathode system; a working cycle is operated, in which, in a first stage, only the first cathode system is maintained at a lower potential than the anode, so that the daughter nuclides precipitate on these cathodes, while the second cathode system is heated. In the next stage of the pptn. cycle, the position is reversed, pptn. taking place on the second cathode system, while the first cathode system is heated. Used esp. for radioactive fission product detection to indicate the presence of a burst fuel can. The arrangement is simple, possessing no moving or revolving parts, but provides high reading accuracy.
